Aura of Tsathogga

**adapted from Aura of Tsathogga by Zoe_Ravendra

Upon casting this spell, a swirling mist of corrosive green vapor engulfs your body.  Any creature that performs a melee attack on the caster takes 2d6 acid damage.  Additionally, the caster gains resistance to acid damage for the spell's duration.

Alternatively, as an action, you can make a melee spell attack against one creature within your reach; a hit does 8d6 acid damage and ends this spell.

Creatures that are immune to acid damage are not affected by this spell.
